Non-parametric Dark Energy Degeneracies
Renée Hlozek, Marina Cortês, Chris Clarkson +1
We study the degeneracies between dark energy dynamics, dark matter and curvature using a non-parametric and non-perturbative approach. This allows us to examine the knock-on bias…
Is the Dynamics of Tracking Dark Energy Detectable?
Bruce A. Bassett, Mike Brownstone, Antonio Cardoso +5
We highlight the unexpected impact of nucleosynthesis and other early universe constraints on the detectability of tracking quintessence dynamics at late times, showing that such d…
Bayesian Estimation Applied to Multiple Species: Towards cosmology with a million supernovae
Martin Kunz, Bruce A. Bassett, Renee Hlozek
Observed data is often contaminated by undiscovered interlopers, leading to biased parameter estimation. Here we present BEAMS (Bayesian Estimation Applied to Multiple Species) whi…
